I think there are enough people putting stops limits up to be seen, when the market is tankin, like november and december, it can spike down and back to 6 in a day or two:
IDIX – I don't think anyone can accurately call the bottom. My feeling is that some hedgies are trying to kill the price now betting IDIX would do a PIPE or secondary by the end of the year.
I agree with your first sentence but not with your second. Based on the CC guidance about cash usage in 2009, I don’t think shorting based on the expectation of a financing deal explains the recent share-price dynamics. However, NVS’ majority stake causes IDIX to have a low float, which makes the stock more volatile than the stocks of most biotech companies with a similar market cap.
